Embodiment 1
[0035] Such as figure 1 As shown, the present invention provides a baby cry recognition method based on a deep neural network, including steps S1 to S8.
[0036] Step S1, collecting baby crying data for training;
[0037] Preferably, before step S3, it may also include:
[0038] Step S2, performing preprocessing for removing noise and background speech on the baby crying data for training.
[0039] Step S3, classifying and labeling the baby crying data for training;
[0040] Preferably, the classification annotations include pathological baby crying and non-pathological baby crying. Specifically, the collection, classification and labeling of baby crying data can be carried out in a professional children's hospital, and about 2 minutes of crying audio is recorded for each baby, and the parenting experts determine the reason for the baby's crying, and classify all the reasons as pathological and non-pathological categories, and mark the audio. After all the recording data ...
Embodiment 2
[0051] Such as figure 2 As shown, the present invention also provides another baby cry recognition system based on a deep neural network, including a first acquisition module 1, a labeling module 2, a first extraction module 3, an initial weight module 4, a cry model module 5, The second collection module 6 , the cry recognizer module 7 .
[0052] The first collection module 1 is used for collecting the baby's cry data for training;
[0053] Labeling module 2, for classifying and labeling the baby crying data for the training;
[0054] Preferably, the labeling module 2 is further configured to preprocess the training baby crying data by removing noise and background speech before classifying and labeling the training baby crying data.
[0055] Preferably, the classification labeling performed by the labeling module 2 includes pathological baby crying sounds and non-pathological baby crying sounds.
[0056] The first extraction module 3 is used to extract the Mel-domain cep...
